Product Description:
The incremental encoder M-3120 004 is designed for connection to the II/O-Lightbus system. The model provides seamless communication for four incremental encoders. It features flexible voltage options and is suitable for various applications requiring high accuracy in motion sensing. This module is a product from Beckhoff. The company is known for its industrial automation technology solutions.
The M-3120 series encoder features a triple power supply configuration with an independent logic voltage of 5 V and additional options for 5 V and 15 V for pick off supplies. The encoders can be connected either with or without complementary channels. It supports both 5 V DC and 15 V DC with a maximum current of 1 A and its connections are resilient to short circuits. The pick off connections are established via a D-SUB connector supporting channels A, A(inverted), B, B(inverted) and C, C(inverted). The encoder input operates with 24 V DC at 10 mA and recognizes input levels from 0 – 8 V as low and 15 – 24 V as high with an input delay of 0.1 ms thanks to its integrated RC filter. The module features a 24-bit binary counter and a limiting frequency of 1 MHz.
The incremental encoder M-3120 004 is built to withstand harsh environments with an aluminum housing. Its dimensions are 170 x 76 x 68 mm and it weighs 560 g. The model’s squareness decoder evaluates signals in 1x, 2x or 4x intervals and the zero impulse latch operates with 24-bit precision. The data transmission rate reaches 2.5 MBaud and offers a fast response rate of 25 microseconds for a 32-bit transmission. The module connects via fiber optics with a maximum distance of 600 meters for glass fiber.
